  <div class="info">
    <i>ol.control.Bar</i> is a panel that contains other controls. Control bar can be nested.
    <br/>
    You can choose the position for the control bar.
    <br/>
    It can group <i>ol.control.Toggle</i> with a toggleOne propertie to have only one activated at a time. You can compose toolbars with it.  
    <br/>
    A sub-bar can be nested to add options/controls visible when the parent <i>ol.control.Toggle</i> is active (see the <a href="map.control.subbar.html">sub-bar example</a>).
